Abstract

A pipette tip (30) for use in automated assay testing systems includes an annular, protruding seal rings (78, 80) on the interior wall of the pipette for engaging sealing surfaces (114, 116) on a probe (100) to provide a resilient seal. The pipette tip also includes a positive stop (66) for assuring proper positioning and alignment of the pipette tip on the probe for facilitating mounting of the pipette tip on the probe while minimizing variation in the loading and unloading forces required. Locator surfaces (32, 48) are provided on the exterior of the pipette tip for precisely aligning the pipette tip in the system rack for positioning the pipette tip relative to the probe.
